Can no longer run processor at 133 fsb

Question

Did I just break my processor or mother board while changing cpu cooling fans?  About a year ago, I received my computer with a K7T266PRO2 mother board and an Athlon 1900+ XP processor.  It was running at 100 fsb and the processor put out 1200 megahertz.  I wanted the full 1.6 gigahertz out of my processor so I changed the clock speed setting in the CMOS from 100 to 133 and enjoyed the next year at that clock speed.  My fan on my cpu fail so I bought a new one from CompUSA for my processor type, and installed it.  Did I push and shove too large installing the fan?  What gives.  The CMOS screamed at me when I booted up that I had incorrect values in the CMOS.  I hit f2 and found myself running at 100 fsb as that is what the default CMOS settings provide.  I changed the clock speed to 133 like before but when I rebooted the computer froze.  I could do nothing with my computer until I cleared the CMOS and reestablished the default 100 fsb setting.  I used this setting for the next three weeks.  I called AMD, the processor manufacturer and they had me check the processor dye for cracks and dents.  As soon as they had me raise the vcore voltage in the CMOS from 1.725 to 1.75 and set the clock speed at 133, the computer rebooted at the full clock speed of the chip!  Yahoo.  But I went into Windows XP and soon XP crashed and exited me out to a screen which said that the computer was shut down to prevent my computer from being hurt.  Please remove any hardware you just installed.  So I went into the CMOS and reset back to 100 fsb.  I called AMD again and told them that I had just discovered that I have been running for the past three weeks with the processor fan on backwards which is what I suddenly discovered while taking the processor apart.  There is a shoulder on the socket which has to mate up with an indentation in the fan heatsink in order for the heat sink to be flush with the chip.  I installed the fan correctly, but to no avail.  Now when I went into windows at 1200 megahertz, the computer froze up after it sits idle for 30 minutes.  I inserted my Windows XP install CD Rom and went to setup repair to fix windows incase there was a corruption.  As a began the setup the computer froze.  So what have I done?  My computer worked optimally until moments after I replaced the cpu cooling fan.  AMD is sending me another cpu.  Do you guys think that is the problem?  What could have happened in the five minutes it took to switch fans (although without knowing it, I put it in 180 degrees backward.)
Any help?

It has happened to me to, so I can with some ackredability suggest you move the CMOS/NVRAM(?) jumper. Power has to be off, while doing this, and I'd suggest you detatch all cables.
